For global installation, use:

sudo pip3 install Django

The installation of Django will give you django-admin command to manage Projects,

$ command -v django-admin
/home/jmutai/.local/bin/django-admin

Check django-admin version using:

$ django-admin --version
3.2.9

Step 3: Create a test Django Application

Create a Django test application by running

mkdir projects
cd projects
django-admin startproject test_app
cd test_app

test_app is the name of our Django Project.

Apply pending migrations

$ python3 manage.py migrate

  Applying admin.0001_initial... OK
  Applying admin.0002_logentry_remove_auto_add... OK
  Applying admin.0003_logentry_add_action_flag_choices... OK
  Applying contenttypes.0002_remove_content_type_name... OK
  Applying auth.0002_alter_permission_name_max_length... OK

  Applying auth.0008_alter_user_username_max_length... OK
  Applying auth.0009_alter_user_last_name_max_length... OK
  Applying sessions.0001_initial... OK

Step 4: Create an Admin Account

Create a Django project superuser account by running the following commands from your Django application directory.

$ python3 manage.py createsuperuser
Username (leave blank to use 'jmutai'): admin
Email address: admin@example.com
Password: <INPUT-PASSWORD>
Password (again): <CONFIRM-PASSWORD>
Superuser created successfully.

Input your admin username, email address, and password.

Step 5: Allow external access to the Django web application (Optional)

Note that by default Django doesn’t allow external access to the application, you need to explicitly define an ACL.

vim test_app/settings.py

Edit the lineALLOWED_HOSTS to whitelist your Computer IP or LAN subnet.

ALLOWED_HOSTS = ['192.168.18.50']

A value of ‘*‘ will match anything:

ALLOWED_HOSTS = ['*']

You can now  start Django application server:

$ python3 manage.py runserver 0.0.0.0:8080
Performing system checks...

Login with created username and password:

The admin page allows you to add other users, add groups, change password e.t.c. It looks like below:

You now have Django Framework installed on your Ubuntu 22.04|20.04|18.04 LTS system.
